INSULATING TROLLEY-W'IBE HANGER.
Specification of Letters Patent.
Patented Feb. 23, 1909.
Application filed February 7, 1908. Serial No. 414,774.
To all whom it may concern:
Be it known that I, LEO W. MORAN, a citizen of the United States, residing at Grafton, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Insulating Trolley-Wire Hangers, and do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
' metal must necessaril My invention relates to improvements in insulating trolley wire hangers, all substantially as shown and described and particularly pointed out in the claim. 7
In the accompanying drawings, Figure 1 is a perspective elevation of the .hanger in one form. Fig. 2 is an enlarged vertical sectional elevation of the hanger seen in Fig. 1. Fig. 3is a cross section of the upper member of the hanger seen in Fig. 2, and at right angles to said figure. Fig. 4 is a longitudinal sectional elevation of the insulating member, and Fig. 5 is a cross section of the lower member of the hanger, modified.
The idea of the invention is to provide an insulating hanger for trolley wires which is sim 1e and cheap in construction and which is a so eifective anddurable in service and is not liable to be broken nor to be worn out by use. To these ends the said hanger is constituted of three members or parts, only, as shown in Figs. 1 and 3,- and which is its simplest form. These parts comprise the upper supporting member A, which has a head 2, a pair 0 lateral arms 3 oppositely divergent from said head, and a substantially cup shaped cavity or socket 4 in its bottom. The said arms have. underlying lips 5 at their respective ends adapted to engage and clam on a supporting wire, or wire from whic the hanger is adapted to be suspended, but which is not shown herein. The entire metallic portion of this han er is preferably made of malleable iron emp oyed, it bein understood that such be like malleable iron in respect to its quahty. so that it will bend or chea ness, but any equivalent metal may be without breaking and be ada ted to shaping as may be required in assem ling the parts. Thus, the ears or lugs 5 have to be bent and clamped upon the cross wire when the hanger is put in place. Otherwise the hanger is brought to the work assembled as seen in Figs. 1 and 3, but in the assembling of the parts further flexibility and responsiveness in the metal is required as will now be seen. Thus, the complete device comprises the lower socket member B and the mtermediate and connecting insulating member C. Said member C is preferably of wood, shaped with'circular outwardly flaring heads 6 at its ends of such taper that when clamped within the respective sockets 4 and 8 it is firmly and permanently incororated with saidparts. To this end the ower part B has a cup shaped socket 8 corres onding to socket 4, and when said insulating piece is (placed in these sockets they are compresse thereupon uniformly all around so as to engage over the said heads 6 'and thus unites the parts A and B permanently bymeans of said insulator G. The trolley wire connection is made with or through threaded stem 10 at the bottom of part B, or a corresponding stem 12 set or threaded into the cup B, instead of being integral therewith.
What I claim is: In trolle hangers, a hanger consisting essentially 0 three pieces comprising separate upper and lower metallic members having corresponding substantially cup sha ed sockets on their inner sides and an insu atin stem having outwardly flaring circular enfis clamped in said sockets, the said lower member having ascrew threaded pro ect.ion at its center and bottom, and the said upper member having lateral arms provided with lips on their ends and bottom adapted tobe clamped on a su porting wire.
In testimony w ereof I sign thls specification. in the presence of two witnesses.
